Backup and Disaster Tolerance

solution.First of all, there is data protection in backup and disaster tolerance. Most backups adopt the tape mode, which features low performance and low cost. Disaster Tolerance uses the disk mode for data protection and data is always online with high performance, high cost; second, backup is a basis in the storage field, and a complete disaster recovery solution must include the backup part. At the same time, backup is also an effective supplement to the disaster recovery solution, because
